I have traveled all over the world using Airbnb. I have also been a host for a decade, hosting people from all over the world. What I have found is there are two kinds of people in this "business" - those who enjoy travel and giving people a good experience in a foreign city / country, and those who are just trying to make $ at any cost. Unfortunately, Chalisa is the later.
I was traveling through Bangkok completely exhausted from jet-lag and a mild illness. I needed to book a place last minute and booked with Chalisa. For various reasons, including that the apt is much further away from public transportation that it first appears on the more general map (which if you know anything about Bangkok's traffic congestion is a big deal), I needed to cancel. All of this happened within 20 minutes. Chalisa wouldn't refund my money. (moderate cancellation policy says 'partial refund', which ends up being about 60% of the cost. So I could 40% back for a button pressing error and a 20 min time lapse.)
As a host, If I had booked in advance and she had lost the potential for other customers I would understand. If hours passed and she prepared the place for my arrival, I would understand. But none of this could have been the case, it all happened too quickly to be possible. She just refused to issue a refund and kept repeating that that's the "business." She couldn't make an argument as to what inconvenience or opportunity cost the booking had caused her and why she should keep the money (because there isn't any), she just kept saying "that's the business" "you're not going to get what you want." Her tone was rude and dismissive, as if she was entitled to the money.
Normally I wouldn't leave a public review over a private dispute. But she was so rude and so unreasonable in the interaction, I just think it speaks to poor character. I thought you should know. BOOK AT YOUR OWN RISK.
